Difference Between Notebook and Desktop CPUs

Since I am going to be getting my first notebook ever, and have very little knowledge on them, could someone please tell me the difference between a notebook and desktop CPU? I don't want to look at the specs and get all confused.

Basically, what I want to know is the differnece between the numbers. Like, if I have a 3.2 GHz Intel CPU in my desktop, what is the equivalent Intel CPU for a notebook?

Thanks for any help I get.

Mmm...I'm not sure of what you want/what you are talking about.

But you may wat to consider this:

PM's are notebook CPUs, and people say that if you multiply the clock speed of the PM x 1.6 or 1.7, you will get the equivalent P4 speed.

So:

My 2.13GHz PM = 3.6GHz P4

I hope this can help you.

Okay, so whatever the processor speed is of the notebook, multiply that by 1.6 or 1.7. If that is true, then great, that is all I wanted to know.

Just remember...it has to be a Pentium M (Centrino)...that trick doesn't work with other processors, just PM's.

Okay. Are only Pentium Ms Centrino Technology?

Yes, pretty much.

Centrino is a package of:
Pentium M + Intel chipset + intel pro wireless

thats all it is, purely for marketing.

that said, take a look at just "Pentium M" labled systems, not "Centrino" because all that means is the wireless card is probably Atheros (which is better than Intel wireless btw according to many people).

also take a look at Turion based laptops, Turion is AMD's answer to Pentium M. Although Turions do deliver slightly less battery life (we're talking minutes, on similar laptops, about 20 minutes per charge..MAX difference), they can do 64-bit, and a few things a bit faster than PM, but except for the 64bit, you'll feel little difference between the 2 options.

With Turions, the speed x 1.6 works too more or less. For instance a 2ghz turion is about 3.2ghz P4.

I think that's a fair measurement. I know this 2.26 PM is lightning-fast compared to the 3.06 P4HT I had in my zd7000.

What kind of thread is this? If you had did some research you wouldn't need to ask people what is the differences between notebook and desktop CPU. So common sense. There heat, size, features, speed, cache memory, and more.

You ever think that you have to learn everything sometime? At one point you didn't know the answer to the question, so I advice you to shut your face. I figure a forum about notebooks is going to know the answer...this is my research.

Is this really true? Where did you hear this from?

I wonder if would apply to AMDs as well, even with lower number, that'd be pretty cool.

But dont think that Laptops only have Pentium M Centrino CPUs...You can get a Laptop with a Pentium 4 or AMD...But if a Laptop has a Pentium 4 3.2Ghz and the Desktop has that too, than its the same thing. From Pentium M to Pentium 4 you x 1.7 but I'm not sure with AMD

amd is 1.6 i reckon.

2.2 is rated at 3500+
2.0 is rated at 3200+
1.8 is rated at 3000+

so roughly 1.6 is a fair thing to call it.

I learned that in this forum after hours and hours of research. That was before I bought my lappy.

Thanks for clarifying everything for me everyone.

Intel Yonah (Core Duo) and AMD X2 CPUs are almost exactly the same clock for clock, the lead varies depending on the task at hand:

You can read this review:

Dothan PM's (lacking certain advanced features of Yonah) will come in slightly behind dekstop A64's, just by a hair.
